[NXC UserInteraction Library]

float createNumberPicker (string questionText_, float minNumber_, float maxNumber_, float selectedNumber_ = -9999, float step_=1 )

Number pickerAsk for a floating-point or integer number with sliding menu interface.

Parameters:
questionText_ Text displayed above the picker. Can be left empty.
minNumber_ Minimal value in the picker
maxNumber_ Maximal value in the picker. This number might be adjusted so that an integer amount of steps towards it is possible from minNumber_
selectedNumber_ (Optional) Default selected value. This is defaulted to minNumber_ if out of range or not one of steps. Default = minNumber_
step_ (Optional) Size of one step. Must be greater than 0. Default = 1

Returns:
float Selected number

NXTPong

A custom-built lego machine for playing pong, featuring two controllers connected to the Mindstorms NXT brick. Programmed using NXC.

Developing in NXC using XCode

After comparing a number of options, I chose NXC as a pretty good alternative to Robot-C. It supports a lot of things like sensor and motor management, playing of sounds, basic 2D and 3D graphics, etc. Most importantly, you can compile your programs from the command line or from XCode. This tutorial assumes knowledge of XCode 4 and of C. The NXC programming guide is a good reference.

Setting up NXC Development on a Mac

This tutorial provides a step-by-step guide for setting up your Mac or Linux machine and your NXT brick for development with NXC. We will use the enhanced NXC firmware in order to enable extended functions for development.

pyCreeper

The main purpose of pyCreeper is to wrap tens of lines of python code, required to produce graphs that look good for a publication, into functions. It takes away your need to understand various quirks of matplotlib and gives you back ready-to-use and well-documented code.

Citations count fails to measure the impact of research

Academic career progress is often judged by so-called "h-index", that measures how much your research is being cited. I recently had a detailed look at what exactly the citations, specifically those reported by Google Scholar, amount to. Only a relatively small fraction of the reported citations corresponded to research being applied or reproduced in a meaningful way.

V-REP, Gazebo or ARGoS? A robot simulators comparison

Let’s have a look at three commonly used open-source simulators for robotics: V-REP, Gazebo and ARGoS, to find out which one suits your project the best.
